As if last weekend's UEFI debacle wasn't bad enough, it now seems the latest C8 kernel (4.18.0-193.14.2) is incompatible with the current ZFSOnLinux packages (0.8.4-1). When booted to the latest kernel, ZFS is inaccessible on my C8 storage server. When I back off to the prior kernel (4.18.0-193.6.3), all is well.
please open an issue on zfsonlinux github: https://github.com/openzfs/zfs/issues and provide them a reproducible testcase.
If a local ZFS system is unavailable to the C8 kernel support folks, I'll be happy to assist them by volunteering my system as a lab rat.
Imho, that's out of CentOS scope, unless some people are willing to work on it with zfsonlinux people.
